The hottest and best-known tablets – While the iPad still leads the way, the tablet-computer market has become a more diverse and competitive one in the past year or so. Users looking to upgrade from their smartphone screen, or get simpler than a laptop, have options that include Apple's offering, as well as new designs from Samsung, Google, Microsoft, Nokia, Asus and others.

iPad Air – The latest version of Apple's industry-leading tablet (they've sold 170 million) went on a serious weight-loss routine. It weighs in at only one pound, down from 1.4, and is 20% slimmer than its predecessor. It starts at $499. On Tuesday Apple also rolled out a new iPad Mini with a high-resolution (or "retina display" in Apple-speak) screen.

Microsoft Surface 2 – The second generation of Microsoft's tablet-laptop hybrid, the Surface 2, was rolled out for sale October 22. Starting at $449 for a 32GB model, the Surface got thinner and more powerful and added a high-definition screen. (It also got rid of the confusing "RT" at the end of its name). The souped-up Surface Pro 2 starts at $899.

Kindle Fire HD – There's a lot more competition now, but Amazon's Kindle Fire was the first tablet to dent iPad's dominance with its smaller size and lower price tag. The new 7-inch Kindle Fire HD costs $199, while a bigger, 8.9-inch Fire HD sells for $299.

Asus Transformer Infinity – They don't have broad name recognition, but Asus has quietly become the third-leading tablet seller (at least in the first few months of 2013). Asus has impressed critics with its Transformer tabs, which have filled the hybrid tablet/laptop slot more successfully than Microsoft's Surface. Its top-of-the-line Transformer Pad Infinity begins around $400.
